Blu-ray Disc (also known as Blu-ray or BD) is an optical disc storage medium. Generally, BD has the same physical dimensions as standard Digital Versatile Discs (also know as Digital Video Discs or DVDs) and Compact Discs (CDs). The main uses of BD can include the storage of data, high-definition video, and games. BD may support storage capacities of around 25 GB per single layered and 50 GB per dual layered disc. Thus, a two-layer Blu-ray Disc can store approximately six times the capacity of a two-layer DVD, or ten times that of a single-layer DVD. The name Blu-ray Disc may be derived from the blue laser (violet-colored) used to read and write this type of disc. Because of the beam's shorter wavelength (about 405 nanometers), substantially more data can be stored on a Blu-ray Disc than on discs configured to be read by lasers having a longer wavelength, such as a red laser (about 650 nm) typically used for DVDs. Other optical storage mediums, such as HD-DVD, may incorporate such blue laser technology to achieve greater storage capacities than standard DVDs and CDs
BD and other high definition (HD) formats thus may bring various improvements to a movie experience, such as high definition video, high quality sound, and interactivity. Table 1 provides an overview of some differences between standard DVD and BD:
As the home video format of choice changed from the Video Home System (VHS) format to DVD, many consumer's existing VHS tape collection were slowly rendered obsolete due to the physically incompatible difference in format. Nowadays, with the transition from standard DVDs to BD, or other HD formats, most consumer electronic players are capable of playing back individual standard DVDs. Some BD players also include upconverting DVD technology.
However, content owners and movie studios already have a lot of content which has been previously authored in the DVD format. Preparing, converting, or reformatting existing DVD authored content to BD can be a costly process involving the authoring, remastering, interactivity development, etc. to take advantage of BD's enhanced video, sound, and interactivity and give consumers a reason to purchase the content in BD format. Some studios may not have the budget to perform such a conversion or the expected return on investment (ROI) may not worth the cost.
Accordingly, what is desired are improved methods and apparatus for solving some of the problems related to distributing content using optical discs, some of which may be discussed herein. Additionally, what is desired are improved methods and apparatus for reducing some of the drawbacks related to distributing content using optical discs, some of which discussed may be discussed herein.

In various embodiments, systems, methods, and computer-readable storage media are provided to repurpose DVD authored content 130 allowing any movie experience, high definition video, high quality sound, and/or interactivity provided by DVD authored content 130 to be accessed via next generation optical disc players. In one embodiment, DVD authored content 130 may be stored as-is on a Blu-ray Disc for playback on a Blu-ray Disc player. The Blu-ray Disc player can be configured to interpret DVD navigations information in DVD authored content 130 and/or reformat audio/video information in DVD authored content 130 allowing any movie experience, high definition video, high quality sound, and/or interactivity provided by DVD authored content 130 to be experienced by users.
BD video content 240 may include digital video. The digital video may be encoded using MPEG-2 compression, MPEG-1 compression, H.264/MPEG-4 AVC, and SMPTE VC-1. The digital video may also include subtitle or subpicture tracks. BD video content 240 may include one or more digital video streams, angles, chapters, or the like. BD audio content 250 may include digital audio. The digital audio may be encoded using Pulse-code Modulation (PCM), Digital Theater System's Coherent Acoustics codec (DTS), MPEG-1 Audio Layer II (MP2), Dolby Digital (AC-3) format, or the like.

BD audio content 250 may include one or more digital audio streams, languages, effects, channels, tracks, or the like. In general, audio, video and other streams can be multiplexed and stored on a Blu-ray Disc in a container format based on the MPEG transport stream, also known as as BDAV MPEG-2 transport stream (M2TS). Blu-ray Disc Video generally uses MPEG transport streams (TS), compared to DVD's MPEG program streams (PS). This may allow multiple video programs to be stored in the same file so they can be played back simultaneously.
BD interactive content 260 may include a wide variety of extra features in addition to BD video content 240 and BD audio content 250. BD interactive content 260 may also be stored on BD 220 separately from BD video content 240 and BD audio content 250. Interactive content can include audio commentary that is timed to a film sequence, documentary features, deleted scenes, photo galleries, storyboards, isolated music scores, trivia text commentary, games, film shorts, TV spots, radio spots and most commonly theatrical trailers, teaser trailers, or the like. Other extras that can be included BD 220 can include motion menus, still pictures, selectable subtitles, seamless branching for multiple storylines, camera angles, and BD-ROM/data files that can be accessed on a computer equipped with a BD-ROM capable drive.
The BD-ROM specification defines at least four Blu-ray Disc player profiles, including an audio-only player profile (i.e., BD-Audio) that does not require video decoding or BD-J. Any video-based player profiles (e.g., BD-Video) are required to have a full implementation of BD-J, with varying levels of hardware support. The BD-Live profile requires a Blu-ray Disc player to have an Internet connection to access Internet-based content. BD-Live features have included Internet chats, scheduled chats with the director, Internet games, downloadable featurettes, downloadable quizzes, and downloadable movie trailers. BD-Live may require local storage in order to handle additional content.
BD authored content 230 may include software. BD player 210 may include Sun Microsystems' JAVA cross-platform software environment. JAVA may be used to implement interactive menus on Blu-ray Discs, games, extra features, or the like. BD player 210 may include a JAVA Virtual Machine. The virtual machine may provide network connectivity, allowing updates via the Internet, adding of content such as additional subtitle languages and promotional features not included on the disc at pressing time, or the like. A version of JAVA called BD-J may be included that provides a subset of the Globally Executable Multimedia Home Platform (GEM) standard. BD-J, or Blu-ray Disc Java, provides a specification supporting Java ME Xlets for advanced content on Blu-ray Disc and the Packaged Media profile of GEM. An Xlet is very similar to a Java applet and is designed to support applications for Digital TV as part of Sun's JAVA TV specification. Xlets can be paused and resumed.
In various embodiments, BD-J Xlets provided one or more of the following capabilities. The invocation of BD-J Xlets may be triggered by events occurring around them—for example, by the selection of a movie title, or by the insertion of a new disc. Xlets in turn can then call other Xlets into play. Security in BDJ may be based on the Java platform security model. Signed applications in JARs can perform more tasks than a non-signed, such as Read/Write access to local storage, network access, selection of other titles on the BD-ROM disc, and control of other running BD-J applications. BD-J has classes that allow synchronization to specific frames in the movie. A BD-J application's GUI can be operated with a remote control with a required set of keys and an optional pointing device. The set of required keys includes at least the keys needed to support the User Operations in HDMV applications. The GUI framework in BD-J includes the HAVi(6) UI framework mandated by GEM. The GUI framework is based on the core of AWT as specified by PBP, but the widget set includes mechanisms for remote control navigation from GEM and easy customization of look and feel from HAVi.
BD-J can include a media framework similar to JMF for the playback of media content related to the BD-ROM disc. The BD-ROM disc may be the prime source for media files, but other sources could be a studio's web server and local storage. BD-J can include standard Java libraries for decoding and displaying images in JFIF (JPEG), PNG and other image formats. These images can be displayed on the Java graphics plane using standard Java graphics functions. An image can also be rendered in the background plane using a BD-J specific package. Text can be rendered using standard Java text functions. These text-rendering functions can be extended with a more advanced text layout manager that integrates with the BD-J UI framework. The text may be rendered using a vector-based font either coming from the disc, the player (default font) or downloaded from the network.
Authenticated applications can use a (signed) permission request file to acquire permissions that go beyond a BD-J sandbox. Permissions can be acquired for: reading and writing to local and system storage; using the network connection (to connect to defined servers); access of the file system on the BD-ROM disc; title selection of other titles on the BD-ROM disc; control of other running BD-J applications; or the like. BD-J applications can use the java.net package to connect to servers on the Internet. Moreover, a Java package for secure connections may be included (JSSE) as part of the BD-J platform. BD-J can also include support for storage.
In various embodiments, DVD authored content 130 may be included on BD 220 allowing any movie experience, high definition video, high quality sound, and/or interactivity provided by DVD authored content 130 to be accessed via BD player 210. In one embodiment, DVD authored content 130 may be stored as-is on a Blu-ray Disc for playback on BD player 210 without the need for further remastering. BD player 210 can be configured to interpret DVD navigations information in DVD authored content 130 and/or reformat audio/video information in DVD authored content 130 allowing any movie experience, high definition video, high quality sound, and/or interactivity provided by DVD authored content 130 to be experienced by users of BD player 220.
For example, in one embodiment, adaptation layer 310 may be embodied as a BD-J application. Adaptation layer 310 may be stored on BD 220 along with DVD authored content 130. Adaptation layer 310 can be configured to interpret DVD navigation information for BD player 210 for one or more standard definition DVDs stored on BD 220. Adaptation layer 310 may convert video and audio information in DVD authored content 120 into Blu-ray format (e.g., BD adapted content 320) for playback using the BD player 210.
In step 420, a Blu-ray Disc is read to obtain DVD authored content. For example, BD player 210 may read BD 220 for information. The read information may include a portion of DVD authored content 130, such as menu information, navigation information, video streams, audio streams, or the like. BD player 210 may read BD 220 automatically, such as when BD 220 is first inserted into BD player 210. BD player 210 may read BD 220 in response to user input. BD player 210 may also read BD 220 in response to adaptation layer 310.
In step 430, DVD navigation information in the DVD authored content read from the Blu-ray Disc is interpreted. For example, BD player 210 may invoke adaptation layer 310 to interpret the DVD navigation information in the DVD authored content read from the Blu-ray Disc. As shown in
In step 440 of
In general, standard definition DVD may use Video Object (VOB) packetizing which transports MPEG2 Program Stream A/V data. Video can be encoded as standard definition (SD) MPEG-2. Audio can be encoded as Dolby AC3, MPEG, DTS, or plain PCM. Blu-ray Disc format may use MPEG-2 Transport Stream.
In one embodiment, adaptation layer 310 may demultiplex VOB data from DVD authored content stored on a Blu-ray Disc (e.g., a stored DVD) into raw audio/video elementary streams. This may occur in real-time or during an offline process. Adaptation layer 310 then may remultiplex the A/V streams into a MPEG-2 Transport Stream (M2TS). As shown in FIG. 5, trans-muxing by adaptation layer 310 may maintain audio and video elementary streams as is, where the original codec used provides the desired quality. Adaptation layer 310 converts the content transport container from Program Stream (PS for DVDs) into M2TS for BD. Adaptation layer 310 may transcode subtitles from DVD subpicture format into BD subtitles or any BD compatible format.
In one embodiment, adaptation layer 310 may transcode video from standard definition (SD) to high definition (HD) using one or more techniques for up-scaling. The up-scaling may be achieved by adaptation layer 310 invoking features of a Blu-ray Disc player itself, using one or more offline tools or techniques, in real-time, or the like. Adaptation layer 310 may include offline tools for up-scaling that provide one or more advantages. For example, quality can be substantially consistent across all players (e.g., quality is not dependent on a player's up-scaling algorithm implementation). Additionally, quality can be fine-tuned for the type of material (vs. one size fits all approach) and have several pass algorithm providing the best quality.
Adaptation layer 310 may incorporate other steps in an A/V transformation. These may include MPEG-2 (A/V) DVD SD transcode and remux to AVC (H.264 and VC1) SD. These may also include MPEG-2 (A/V) DVD ES decoding and format conversion to HD Base band (e.g., all acceptable BD resolutions). These may also include transcode and Remux AVC (HD H.264 L4.1 and VC1 level 3) and audio transcode optional from MPEG2 L1 or Dolby AC3 to Dolby Plus or other BD advanced audio formats.
Generally, the DVD format allows a limited number of colors for buttons and subtitles. Accordingly, adaptation layer 310 may incorporate dithering to allow for more colors. In one embodiment, during the conversion to BD format, adaptation layer 310 may employ a 32 bit gradient to provide enhanced colors for displayed elements.
In some embodiments, Adaptation layer 310 may analyze and parse subtitles so that a textual representation is extracted. The text representation may be used to perform searches and generate new more pleasant hi-res subtitles. Additionally, subtitles contrast may be enhanced so that they are well contrasted with the currently displayed video.
Returning to
In various embodiments, as several DVDs may be bundled into a single BD, an additional hierarchy may be created to introduce the concept of root navigation. Such a hierarchy can be introduced to provide hierarchical access to each of the stored DVDs starting from a root menu.
A DVD navigator virtual machine (e.g., DVD navigator application 620) may be provided to handle this layer and ensure the compatibility with a BD-J Top Level Application 610. BD-J Top Level Application 610 may be embodied as adaptation layer 310. In further embodiments, BD-J Top Level Application 610 may provide access to BD advanced features (e.g., BD Application Additional Features 630). These may include features such as seamless menu loops and seamless audio switch. In addition to have a BD menu to access the regular DVDs, extra BD features can be added (e.g. games, featurettes, BD-Live applications). Some BD-J Application features that may be added automatically can include search in the subtitles, multiple subtitles at the same time, slow play with correct pitch, or the like.
